FWIW, after the RefProps/RefParams discussion, I now agree that EPRs are not necessarily identifiers. But I don't see them as addresses either, since addresses are identifiers[1]. IMO, the best way to think of this is with the EPR as a 2-tuple with an identifier and some contextual state, in exactly the same way we think of http URIs and cookies. So, I believe that an EPR is an identifier iff it contains no contextual state, i.e. no RefParams. > One remaining question is whether EPR (as addresses) should be URIs but I > think this should be opened as a separate issue. I disagree. I think it's part and parcel. But no biggie, as long as it gets its day in court. 8-) So unfortunately, I'm -1 on the proposal. And I'd consider writing up my own proposal, but it involves removing RefProps (to provide a single identifying data element), and I don't see that flying just yet. But we'll see where DavidB and Hugo get on that front ... [1] http://lists.w3.org/Archives/Public/public-ws-addressing/2004Nov/0588.html Mark. -- Mark Baker.
